I have a decent laser pointer but it is pretty old. It runs well on Eneloops. Eneloops have solved a lot of life challenges for me. For instance, I’ve been using rechargeable electric toothbrushes for years. They never last long and the internal battery seems to be the culprit. So I bought a cheap one that runs on a pair of AA cells. I loaded it with Eneloop Pros. Not only has it outlasted every previous model I’ve owned, it is doing so with consistent performance.
